The signals are numbered or the names of the signals are defined, for example, the signals in the uplink direction are S01 and S02, the signals in the downlink direction are X01 and X02, and the types of the signals can be ignored here, and the signals are distinguished only by the numbers so as not to be repeated. In addition, it is also necessary to define an identifier for each configuration item, set a data type, an attribute, a data length, and the like, and the method is applicable to all sub-modules that implement functions by a data configuration method.
1) For the track section submodule, the specific data configuration method is as follows:
firstly, according to the design of an example station yard graph in FIG. 5, the lengths of track sections are configured, and particularly, the lengths of the track sections in three sections, namely, a turnout front section, a turnout rear section and a turnout rear section are recorded; for a turnout-free logical section, the length of a track section is recorded, and a front track section and a rear track section of the track section are determined according to the physical direction from left to right; for the turnout section, the turnout is taken as the center, the track section connected with the front turnout section is the front track section, the track section connected with the rear side of the turnout is the rear reversal track section, and the track section directly connected with the rear of the turnout is the rear positioning track section, so that the front-rear link relation of the track sections is realized, the simulation calculation of the position of the train is also the basis, and if the configuration of the part is wrong, the simulation train can prompt derailment when the track line runs.
Examples are as follows: taking 4G as an object, the front track section is 6G, and the rear track section is 2G; with reference to P02, the front track section is 5G, the rear positioning track section is 7G, and the rear inverted track section is P01.

firstly, configuring a track section where a transponder is located, offset of the transponder from the starting point of the track section where the transponder is located, and an index of a transponder message or an LEU to which the transponder belongs, ensuring that a simulation train receives the message of the transponder in a transponder receiving window, continuously receiving two transponders, and establishing positioning for the simulation train. The passive transponder needs to configure a message; the active responder needs to configure the index of the belonged LEU, so that the LCS safety logic platform and the LCS interface platform transmit responder message channels in one-to-one correspondence, variable messages are sent in real time according to the display state of the annunciator, the simulation train receives the messages with effective mobile authorization, and the ITC operation mode is upgraded after other conditions are met.
Examples are as follows: VB04 is taken as an object, the located track unit is 5G, the offset of the responder from the starting point of the located track section is the center kilometer post of the responder minus the kilometer post of the starting point of the left end of 5G, the responder message is empty, and the index of the belonged LEU needs to refer to an LEU cabinet terminal distribution table. And the FB04 is taken as an object, the responder message is required to be configured, the index of the belonged LEU is not required to be configured, and the rest configuration methods are the same and are not described again.
